Tāutanga
1. Te tāutanga o te kōhao whakarewa wera. Ko tēnei tikanga e whakamahia whānuitia ana mō ngā whakaritenga DN20-DN110mm. Ko te tukanga whakahaere motuhake koia tēnei:
(1) Whakamahia he kutikuti paipa hei tapahi i te paipa kia rite ki ngā hiahia tāutanga;
(2) Tohua te hohonutanga o te paipa hei tāutanga;
(3) Whakamahanahia te mīhini whakarewa wera ki te 210℃
(4) Whakamahanahia ngā paipa me ngā hononga i te wā kotahi, kātahi ka whakauru i ngā tūhono (tāria he wā poto i muri i te whakanoho i ngā tūhono ka tukuna. Kaua e nekehia i te wā e whakamahana ana, e tāuta ana i ngā tūhono me te whakamatao ana)
(5) Whakamatao ā-tūroa:
(6) Kia oti te hanganga, ka taea te hiri i te paipa me te whakamahi i muri i te whakamātautau pēhanga anake.
2. Te tāutanga o te papa whakarewa wera, ko ngā whakaritenga DN160-DN1200mm te tikanga whānui, ko ngā mahi e whai ake nei:
(1) Whakatakotoria ngā paipa PE e rua hei hono ki runga i te taputapu whakarewa wera i te wā kotahi (ka taea te whakakapi i te rawhi kia rite ki te diameter o te paipa hei tāuta), ka hiki i te pito kē atu o ia paipa ki te mata wai kotahi mā te whakamahi i te awhi paipa;
(2) Whakamahia he mīhini mira hiko hei tapahi i ngā mata pito o ngā paipa kia papatahi kia tino ōrite ai ngā mata e pā ana ki ngā paipa e rua.
(3) Whakaarahia te pereti whakamahana hiko ki te 210 nekehanga, whakatakotoria ki waenganui o ngā pito paipa e rua, ka whakahaere i te taputapu waipēhi hiko kia tino pā ngā pito paipa e rua ki te pereti whakamahana hiko, kia wera ai i te wā kotahi;
(4) Tangohia te pereti whakamahana ka whakahaere anō i te taputapu waipēhi kia tino piri ngā pito o ngā paipa rewa e rua, kia mau ai te taputapu waipēhi (kia kore ai e hoki whakamuri);
(5) Puritia mō tētahi wā whakamatao, ka tukuna, ā, ka oti te mahi;
(6) Kia oti te hanganga, me paahitia te whakamātautau pēhanga i mua i te tanumanga me te whakamahinga; (Kia mahara: Me waiho te whakamātautau pēhanga hei whakamātautau pēhanga wai!)
(7) Me mahi i ngā mahi ārai hau i te wā e whakamahana ana i te paipa, ā, i te wā e whakamatao ana, me whakamatao haere te paipa, kaua e tere.
3. Hononga hanumi hiko (te diameter o te paipa e tika ana dn≤630mm):
(1) Whakauruhia te paipa PE ki roto i te hononga paipa hanumi hiko;
(2) Honoa ngā waea e rua o te mīhini whakakotahi hiko motuhake ki ngā pou pai me ngā pou kino o te hononga paipa whakakotahi hiko;
(3) Whakakāhia te hiko hei whakamahana i te waea whakamahana hei whakarewa i te PE i te pa o roto;
(4) I muri i te whakamatao:
(5) Kia oti te hanganga, me paahitia te whakamātautau pēhanga i mua i te hiri me te whakamahi i te paipa.
4. Hononga flange
5. Hononga ipu-kirihou
6. Te tāutanga hononga āhua-nohoanga, he tino whai hua ki te whakaoti rapanga o te hurihanga o ngā paipa matua
